Pennsylvania Game News - December 2015 - 58

700 - which came out in 1962 and featured a push-feed action, plunger ejector
and C-clip extractor - was building a
strong following.
Meanwhile, the Winchester Model 70,
which had maintained a great reputation
for nearly 30 years, was losing customers
since its cost-saving redesign in 1964.
The successful Savage Model 110,
which had been around since 1959, and
the Weatherby Mark V, a big-money gun
with a flashy reputation and its own line
of magnum cartridges, also claimed their
share of the market.
With all the competition, bringing out
a new bolt-action rifle might have seemed
a gamble.
But I believe Ruger felt the right combination of old and new designs would
win over many sportsmen.
The name Model 77 was selected because the rifle's main competition in the
market would come from the Remington
700 and Winchester Model 70.
In his design, Bill Ruger incorporated
investment casting for the receiver and
bolt.
This technique used a mold formed
around a pattern of wax or similar material
that then was removed by melting, and it
allowed for making small, accurate castings in refractory alloys. Investment casting proved to provide superior strength
and less follow-up machining work.
This resulted in a less-expensive product compared to the cost of machining a
piece of bar stock from scratch.
The Model 77 kept the Mauser extractor and twin locking lugs, cocked on opening, but incorporated the push-feed design
when chambering a cartridge.
The ejector was a spring-loaded
plunger in the bolt face that would eject
58

spent cases the moment the case mouth
was clear of the action.
To handle any rogue gases from a rare
pierced primer or ruptured case, and vent
them away from the shooter, the bolt had
three oblong holes machined in the body.
The bolt sleeve had a wide deflecting
flange on the shooter side of the rifle, and
the forward section of the receiver had a
hole drilled through it on the bolt handle
side of the action, at the junction of the
bolt face and chamber.
Other great features were the accessible tang safety, which not only blocked
the trigger, but also the sear - and could
be used by both right- and left-handed
shooters.
The only thing I don't like about this
two-position safety is that, when on safe,
it does not lock the bolt in battery.
But then again, extracting a live round
with the safety off is certainly not as safe
as having it on.
The scope bases on the Model 77 are
integral with the action, which makes a
stronger attachment for scope rings, as
compared to separate bases held in by
screws. The integral mounts also allow
a scope to be mounted lower for a better
cheek-weld on the stock.
A round-top model drilled and tapped
to accommodate standard scope mounts,
which was especially accommodating for
the longer target scopes such as Unertl and
Redfield 3200 series scopes, was made
up until 1982.
The Model 77 also had an easily accessible hinged floor plate that enabled the
magazine to be emptied quickly.
Some variations had open sights consisting of a contoured ramp flip-down
rear sight on the barrel that allowed for
windage and elevation to be adjusted
somewhat, and an adjustable, ramp-styled
barrel band front sight.
